This is an example custom XCF file for Four Js GAS. In this example I've set custom environment variables, set the path for the working application directory, specified a specific module and passed in a parameter. One handy use of an XCF file like this is that I can setup several for example say I have 5 weighbridges and I run a 4Js application to capture the weight etc of each truck as it passes over the weighbridge I can setup an XCF for each weighbridge passing in the parameter 1, 2, 3, to the same program weighbridge.42r <APPLICATION Parent="defaultgdc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.4js.com/ns/gas/2.20/cfextwa.xsd"> <EXECUTION AllowUrlParameters="TRUE"> <ENVIRONMENT_VARIABLE Id="DBDATE">DMY4/</ENVIRONMENT_VARIABLE> <ENVIRONMENT_VARIABLE Id="GREDIR">f:\PROGRAM FILES (X86)\FOURJS\GRE\</EN
